When L died they replaced him with someone that was almost exactly like him, no doubt they could have done it with Light.

the anime ended with light.

It was getting dragged out and you know it. If they tried to come up with anything else it would have been shit. And we are off topic so much right now.

yeah we are. but my point is if at any time our main (MAIN) character dies, in this case light, the show would end. so if he died 10 episodes earlier, that it, deathnote ended there. the other episodes wouldnt exist.
